Re: Would inside edge wear on both trailer tyres indicate bent axel?

Cant imagine its anything other than a bent axle. Draw a series of lines across each tyre with chalk tow the boat around the block and see where the chalk is removed should be the inside of each tyre. Rotate the axle on the axle plates 180 degrees and repeat the chalk test, should rub the chalk off the outside this time. Leaving the axle in this position may bring it back right but the test would indicate that the axle is bent and may need replacing and maybe with a heavier rated one.

If you are using one of those over the boat tie down straps that can be cranked up very tight and its located on the trailer frame just behind the axle insure it is not over tightened after the boat is loaded for your trip. The picture shown in your post would indicate to me the trailer would be adequate for the boat and motor package.

Tks Mark,
Don't have tie the "over the boat" tie downs, just 2 at the rear on the transom,
Last year the roads along the way were very poor due to the flooding, pot holes etc
Will research if Dunbier sell heavier axles

Gary you don't have to use a Dunbier axle if its required there are plenty of trailer component resellers in the Brisbane area axles are cheap.

Re: Would inside edge wear on both trailer tyres indicate bent axel?

Hi Mark
Just got off the phone to a repair guy who does trailers for pro's down our SE, (Robe)
I'm about 3000km from Brisbane unfortunately,
I will take a drive an get a quote, for local work he thinks the standard axle is OK but the trip each year of 3000km to Lucinda should be supported by a solid axle
Its a couple hundred km away but it should be better work than local, Ive already thrown $2000 at the trailer and hasn't really solved the problems
Actually got my Motor serviced in QLD before I left, saved $200 already.........If you own a boat, QLD is the place to be

Re: Would inside edge wear on both trailer tyres indicate bent axel?

Hadn't thought of that, actually starting to look like flex as when the boat was unloaded, the wheels are starting to become vertical again
A lot will depend on the quote for a solid axle
Hope to make the trip for a quote in a week or 2

Re: Would inside edge wear on both trailer tyres indicate bent axel?

Ok they are wearing on the inside more than the outside.......how many km will it take to wear them out?
How long will it take to wear them out?
If you are thinking 5 years for a set of tyres for replacement, the cost involved in treating the problem will probably take 3 sets of tyres.

AVOID welding anything to your axle.

If the axle is badly underweight for the trailer and load then take it up with the manufacturer, they should not have offered you a trailer with an underweight axle.

Re: Would inside edge wear on both trailer tyres indicate bent axel?

Tks Jack,
Pretty much, 2 years for a set of tyres, that is, 2 trips from Adelaide to Lucinda,
First trip wasn't too bad but the tyre wear increased this trip to the extent I needed to replace them
Bout the boat 6 years ago, all was OK until I did the long hauls up north and, with a load in the boat

I am interested in your comment "AVOID welding anything to the axle"

What concerns you about welding an upper brace in compression? The axle tube is low carbon steel and has the stubs welded in the ends.
